We bake all of our boards at 220 degrees F for two hours. This bakes out all the moisture. Blow off the parts prior to placing in the oven.

Only use the shop air if it is clean and dry. I know from experience that one can get water and a little oil from the compressor in the air lines. We are in a drier climate with humidity levels in the 25%-35% range on average. All we do is let the

steve- once again I mention that the lead that is actually in the water is in solution i.e. the lead is in a molecular form that has attached to a H2O molecule. To have a minimum of lead that is below the regulated ppm, there cannot be any chunks,

We use an evaporator, so that we only have a sludge of flux residue and solder metal to dispose of via the hazmat handling service. We also route stencil washer waste water into it. We use a 30 gallon drum and have it hauled off maybe twice a year,

All valuable insights are provided by the other posters to this thread. I'd like to add a bit more, if I may. Being environmental friendly is a must. I would not advocate dumping toxic metals to the sewer. In a past worklife, a steel mill, I was r

Before entering the cleaner, the board should reach almost temperature of first pre-wash module (are you using DI water washing machine?), if water cleaner, normally the temp of prewash spry is set from 45 C� to 55 C�. (or it could be 10�C higher, bu

So let's see, Cost of Ownership = [[Equipment cost + Setup]+[Operating costs]] / [Yield*Throughput*Utilization], where 'Operating costs' include: chemicals, water, electricity, DI tanks, filters, recycling costs, etc.

If the batch cleaner is truly closed loop, then 100% of all of the process fluid (water) is captured, filtered (particulate, carbon, resin) and reused. This answer is based on a traditional closed-loop batch cleaning system with an integrated water

The specific answer depends on what your specific application includes. #1: What are you removing? (solder paste, adhesives) #2: What are you cleaning? (stencils, screens, misprints, pallets) #3: What type of machine are you using? (Spray-in
